KEROSENE-BURNER- .EOR RANGES.

Application filed March 19,

burner which ma be installed in ran 'es or like stoves or furnaces.

Another object of the invention is to pro vide means for heating the kerosene after introduction into the fire box of the stove whereby to gasify the kerosene.

A further object is to provide means for reheating the gas just prior to its introduction into the burner proper and still another object is to provide a stabilizing chamber into which the gasified kerosene shall be directed and from which gas shall pass through the discharge nipple, said stabilizing chamber insuring. a steady and continuous flow of gas under minimum pressure.

Another object is to provide means to spread the gas flame issuing from the discharge nipple of the burner so that the flame may permeate and extend throughout the entire fire box of the range.

Still another object is to provide improved means whereby the pipe may be cleaned of soot or other foreign matter.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional view of a range showing my improved kerosene burner applied thereto;

Fig. 2 is a longitudinal sectional view on the line 2-2 of Fig. 1, and

Fig. 3 is a fragmentary section of a blowout valve.

Referring to these drawings, designates the range itself with a fire box 11 of any suitable character. Disposed within the fire box is a stabilizing chamber 12, which terminates at its upper end in a burner nipple 13 having a central opening, the discharge through this burner nipple being reg- Specification of Letters Patent.

ulated by a needle valve 14: extending down through the stabilizing chamber 12.

Entering the fire box is a pipe 15 by which kerosene is introduced to the burner. This pipe 15 is provided. with a suitable valve 15 whereby the flow of kerosene may be regulated and the pipe is intended to be con nected to any suitable reservoir. The pipe 15 enters the fire box and then extends upwardly therein and extends across and approximately over the burner. Mounted upon the transversely extending portion 16 of the pipe 15 is a spreader 17 which is disposed directly above the burner nipple 13. This spreader serves to disseminate the flame and also forms a protection to the pipe 16. It further acts to conduct heat to the pipe 16, thereby changing the liquid kerosene into a gaseous state. Of course the spreader 17 protects the pipe 16 against direct contact with the flame.

The pipe 16 extends across the fire box, then downward, and transversely, but to one side of the burner nipple 13, then it extends again downward and transversely as at 18. This transverse portion 18, while it is disposed slightly above the burner nipple 13, is to one side of this burner nipple, as illustrated in Fig. 2, and this portion 18 is connected by two pipes 19, to the stabilizing chamber 12. At the extremity of the pipe 18, there is provided an outlet valve 20 controlled by means of a valve spindle 21 and when this outlet valve 20 is open, compressed air may be blown through the pipe 15 which will blow out through the opening controlled by the valve 20 any soot or other foreign matter which may collect within the burner pipe.

It will be seen that with this construction the liquid kerosene or like fuel is first transferred into a vapor in the portion 16 of the pipe which is heated by conduction through the spreader 17. This gasified or vaporized fuel is then conducted down to the portion 18 where it is again heated by the heat of the flame discharged from the nipple 13. The gas is then conducted into the stabilizing chamber 12 and discharged from the nipple 13. This stabilizing chamber I regard as of great importance, as it insures a steady and continuous flow of gas, even under minimum pressure.

It will be seen that my burner is very simple, that it can use kerosene or other hydro-carbons of like character, that the fuel Will be placed in the very best condition possible for combustion, and that the pipes may be readily cleaned of soot or other foreign matter.

I claim In an oil burner of the character de scribed, a stabilizing chamber having a discharge nozzle a valve carried by and extending through the chamber into the nozzle for controlhng the dlscharge of vapor from the nozzle, means conveying vaporized 011 through the stabilizing chamber and for supporting, said chamber including a pipe disposed in close proximity to the flame issuing 15 from the nozzle and pipes carried by the first named pipe and connecting the chamber to the first mentioned pipe.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses. 20
